871 | # info into compilelog, as well |
872 | # as mirroring to screen |

875 | # compiles into 'a', saves compilation |
876 | # info into compilelog, being silent |

878 | |
879 | %prompt perlcc a.p -C a.c -gen # generates C code (into a.c) and |
880 | # stops without compile. |
881 | |
882 | %prompt perlcc a.p -L ../lib a.c |
883 | # Compiles with the perl libraries |
884 | # inside ../lib included. |
885 | |
886 | =head1 DESCRIPTION |
887 | |
888 | 'perlcc' is the frontend into the perl compiler. Typing 'perlcc a.p' |
889 | compiles the code inside a.p into a standalone executable, and |
890 | perlcc A.pm will compile into a shared object, A.so, suitable for inclusion |
891 | into a perl program via "use A". |
892 | |
893 | There are quite a few flags to perlcc which help with such issues as compiling |
894 | programs in bulk, testing compiled programs for compatibility with the |
895 | interpreter, and controlling. |
896 | |
897 | =head1 OPTIONS |
898 | |
899 | =over 4 |
900 | |
901 | =item -L < library_directories > |
902 | |
903 | Adds directories in B<library_directories> to the compilation command. |
904 | |
905 | =item -I < include_directories > |
906 | |
907 | Adds directories inside B<include_directories> to the compilation command. |
908 | |
909 | =item -C < c_code_name > |
910 | |
9636a016 |
911 | Explicitly gives the name B<c_code_name> to the generated file containing |
912 | the C code which is to be compiled. Can only be used if compiling one file |
913 | on the command line. |
52cebf5e |
914 | |
915 | =item -o < executable_name > |
916 | |
917 | Explicitly gives the name B<executable_name> to the executable which is to be |
918 | compiled. Can only be used if compiling one file on the command line. |
919 | |
920 | =item -e < perl_line_to_execute> |
921 | |
922 | Compiles 'one liners', in the same way that B<perl -e> runs text strings at |
923 | the command line. Default is to have the 'one liner' be compiled, and run all |
924 | in one go (see B<-run>); giving the B<-o> flag saves the resultant executable, |
925 | rather than throwing it away. Use '-argv' to pass arguments to the executable |
926 | created. |
927 | |
9636a016 |
928 | =item -b |
929 | |
930 | Generates bytecode instead of C code. |
931 | |
932 | =item -opt |
933 | |
934 | Uses the optimized C backend (C<B::CC>)rather than the simple C backend |
935 | (C<B::C>). Beware that the optimized C backend creates very large |
936 | switch structures and structure initializations. Many C compilers |
937 | find it a challenge to compile the resulting output in finite amounts |
938 | of time. Many Perl features such as C<goto LABEL> are also not |
939 | supported by the optimized C backend. The simple C backend should |
940 | work in more instances, but can only offer modest speed increases. |
941 | |
52cebf5e |
942 | =item -regex <rename_regex> |
943 | |
944 | Gives a rule B<rename_regex> - which is a legal perl regular expression - to |
945 | create executable file names. |
946 | |
947 | =item -verbose <verbose_level> |
948 | |
ca24dfc6 |
949 | Show exactly what steps perlcc is taking to compile your code. You can |
950 | change the verbosity level B<verbose_level> much in the same way that |
951 | the C<-D> switch changes perl's debugging level, by giving either a |
952 | number which is the sum of bits you want or a list of letters |
953 | representing what you wish to see. Here are the verbosity levels so |
954 | far : |
52cebf5e |
955 | |
956 | Bit 1(g): Code Generation Errors to STDERR |
957 | Bit 2(a): Compilation Errors to STDERR |
958 | Bit 4(t): Descriptive text to STDERR |
959 | Bit 8(f): Code Generation Errors to file (B<-log> flag needed) |
960 | Bit 16(c): Compilation Errors to file (B<-log> flag needed) |
961 | Bit 32(d): Descriptive text to file (B<-log> flag needed) |
962 | |
963 | If the B<-log> tag is given, the default verbose level is 63 (ie: mirroring |
964 | all of perlcc's output to both the screen and to a log file). If no B<-log> |
965 | tag is given, then the default verbose level is 7 (ie: outputting all of |
966 | perlcc's output to STDERR). |
967 | |
968 | NOTE: Because of buffering concerns, you CANNOT shadow the output of '-run' to |
969 | both a file, and to the screen! Suggestions are welcome on how to overcome this |
970 | difficulty, but for now it simply does not work properly, and hence will only go |
971 | to the screen. |
972 | |
973 | =item -log <logname> |
974 | |
975 | Opens, for append, a logfile to save some or all of the text for a given |
976 | compile command. No rewrite version is available, so this needs to be done |
977 | manually. |
978 | |
979 | =item -argv <arguments> |
980 | |
ca24dfc6 |
981 | In combination with C<-run> or C<-e>, tells perlcc to run the resulting |
52cebf5e |
982 | executable with the string B<arguments> as @ARGV. |
983 | |
984 | =item -sav |
985 | |
986 | Tells perl to save the intermediate C code. Usually, this C code is the name |
987 | of the perl code, plus '.c'; 'perlcode.p' gets generated in 'perlcode.p.c', |
ca24dfc6 |
988 | for example. If used with the C<-e> operator, you need to tell perlcc where to |
52cebf5e |
989 | save resulting executables. |
990 | |
991 | =item -gen |
992 | |
993 | Tells perlcc to only create the intermediate C code, and not compile the |
994 | results. Does an implicit B<-sav>, saving the C code rather than deleting it. |
995 | |
996 | =item -run |
997 | |
998 | Immediately run the perl code that has been generated. NOTE: IF YOU GIVE THE |
999 | B<-run> FLAG TO B<perlcc>, THEN THE REST OF @ARGV WILL BE INTERPRETED AS |
1000 | ARGUMENTS TO THE PROGRAM THAT YOU ARE COMPILING. |
1001 | |
1002 | =item -prog |
1003 | |
1004 | Indicate that the programs at the command line are programs, and should be |
1005 | compiled as such. B<perlcc> will automatically determine files to be |
1006 | programs if they have B<.p>, B<.pl>, B<.bat> extensions. |
1007 | |
1008 | =item -mod |
1009 | |
1010 | Indicate that the programs at the command line are modules, and should be |
1011 | compiled as such. B<perlcc> will automatically determine files to be |
1012 | modules if they have the extension B<.pm>. |
1013 | |
1014 | =back |
1015 | |
1016 | =head1 ENVIRONMENT |
1017 | |
1018 | Most of the work of B<perlcc> is done at the command line. However, you can |
1019 | change the heuristic which determines what is a module and what is a program. |
1020 | As indicated above, B<perlcc> assumes that the extensions: |
1021 | |
1022 | .p$, .pl$, and .bat$ |
1023 | |
1024 | indicate a perl program, and: |
1025 | |
1026 | .pm$ |
1027 | |
1028 | indicate a library, for the purposes of creating executables. And furthermore, |
ef712cf7 |
1029 | by default, these extensions will be replaced (and dropped) in the process of |
52cebf5e |
1030 | creating an executable. |
1031 | |
1032 | To change the extensions which are programs, and which are modules, set the |
1033 | environmental variables: |
1034 | |
1035 | PERL_SCRIPT_EXT |
1036 | PERL_MODULE_EXT |
1037 | |
1038 | These two environmental variables take colon-separated, legal perl regular |
1039 | expressions, and are used by perlcc to decide which objects are which. |
1040 | For example: |
1041 | |
1042 | setenv PERL_SCRIPT_EXT '.prl$:.perl$' |
1043 | prompt% perlcc sample.perl |
1044 | |
1045 | will compile the script 'sample.perl' into the executable 'sample', and |
1046 | |
1047 | setenv PERL_MODULE_EXT '.perlmod$:.perlmodule$' |
1048 | |
1049 | prompt% perlcc sample.perlmod |
1050 | |
1051 | will compile the module 'sample.perlmod' into the shared object |
1052 | 'sample.so' |
1053 | |
1054 | NOTE: the '.' in the regular expressions for PERL_SCRIPT_EXT and PERL_MODULE_EXT |
1055 | is a literal '.', and not a wild-card. To get a true wild-card, you need to |
1056 | backslash the '.'; as in: |
1057 | |
1058 | setenv PERL_SCRIPT_EXT '\.\.\.\.\.' |
1059 | |
1060 | which would have the effect of compiling ANYTHING (except what is in |
1061 | PERL_MODULE_EXT) into an executable with 5 less characters in its name. |
1062 | |
9636a016 |
1063 | The PERLCC_OPTS environment variable can be set to the default flags |
1064 | that must be used by the compiler. |
1065 | |
1066 | The PERLCC_TIMEOUT environment variable can be set to the number of |
1067 | seconds to wait for the backends before giving up. This is sometimes |
1068 | necessary to avoid some compilers taking forever to compile the |
1069 | generated output. May not work on Windows and similar platforms. |
1070 | |

1071 | =head1 FILES |
1072 | |
1073 | 'perlcc' uses a temporary file when you use the B<-e> option to evaluate |
1074 | text and compile it. This temporary file is 'perlc$$.p'. The temporary C code is |
1075 | perlc$$.p.c, and the temporary executable is perlc$$. |
1076 | |
1077 | When you use '-run' and don't save your executable, the temporary executable is |
1078 | perlc$$ |
1079 | |
1080 | =head1 BUGS |
1081 | |
9636a016 |
1082 | The whole compiler suite (C<perlcc> included) should be considered very |
1083 | experimental. Use for production purposes is strongly discouraged. |
1084 | |
52cebf5e |
1085 | perlcc currently cannot compile shared objects on Win32. This should be fixed |
9636a016 |
1086 | in future. |
1087 | |
1088 | Bugs in the various compiler backends still exist, and are perhaps too |
1089 | numerous to list here. |
